To add some to your page, just visit The Gap's Vote For Website, click on the buttons page, then see which ones stand out to you the most. Once you find one that you like, just move your cursor over the button and you should see an option to "Add to Facebook." Once you click on this option, it will navigate you to your Facebook's app page.

What I love about these buttons is the fact that they aren't only great for the election, but they can be used year-round, like one of my faves "Vote For Rollerblading!"
